Just a heads up for anyone that uses the TWAI interface.

With the esp-idf 5.5.1 the old TWAI API has been deprecated and replaced with a new API.
Hopefully the same problems that have occurred (and still seem to be unresolved) with the i2c interface won ́t appear. So far so good..

The old API still works (for now I guess) but in the Espressif documentation there are lots of bugs in the code samples.

The example in the esp-idf tree are correct and do compile (https://github.com/espressif/esp-idf/blob/master/examples/peripherals/twai/twai_network)

Hope this helps someone.
